    Egyptian CRS: quick reference

    Egypt historically works on the Egypt 1907 datum (Helmert 1906 ellipsoid) with a Transverse Mercator split into three belts: Red for the centre (31°E), Blue for the east and Sinai (35°E), Purple for the west (27°E). Modern GNSS work observes on WGS84 and is often delivered in UTM zones 35/36.

    The costliest site error is mixing datums: a point moved from a legacy sheet to a GPS rover without the shift lands ~130 m off. This tool applies the published shift (EPSG::1148) both ways and warns when a point falls outside Egypt — the classic symptom of swapped axes.

    For centimetre-grade work — stake-out, control networks, Scan-to-BIM — you need geodetic observation and a local fit. See our surveying & geodesy services or request a scoped quote.

    Key coordinate systems across the Arab world

    Each country runs one or more national datums: the Gulf family (Ain el Abd, Nahrwan, PSD93, Qatar 1974), the Levant (Deir ez Zor, Palestine 1923), and the Maghreb (Nord Sahara, Carthage, Merchich), alongside Egypt’s 1907 belts and modern ITRF frames. Below is a selection of the most-used systems — the tool supports 195; open your country’s page for its full list.

    FAQ

    Which systems and countries does the tool cover?
    It covers 195 coordinate systems across 22 Arab countries: Egypt 1907 belts, Ain el Abd (Saudi/Bahrain), Nahrwan (UAE), Karbala (Iraq), PSD93/Fahud (Oman), Qatar 1974/QND95, Deir ez Zor (Syria/Lebanon), Palestine 1923, Libya LD79/LGD2006, Nord Sahara (Algeria), Carthage (Tunisia), Merchich (Morocco), and more — plus WGS84 and the UTM zones. Pick the source system from a list grouped by country.
    What is the Egyptian Red Belt?
    The Red Belt is an Egyptian Transverse Mercator projection on the Egypt 1907 datum with central meridian 31°E (EPSG:22992). It covers central Egypt and the Nile Valley and is the most common grid on Egyptian survey sheets.
    When do I use the Blue or Purple Belt?
    Blue (EPSG:22991, 35°E) for eastern Egypt and Sinai; Purple (EPSG:22993, 27°E) for the west; Extended Purple (EPSG:22994) for the south-west. Follow the project’s reference sheets.
    Why does GPS disagree with old sheet coordinates by ~100 m?
    GPS reads WGS84 while legacy Egyptian sheets sit on Egypt 1907 — the datums differ by roughly 130 m in Egypt. A proper datum shift is required, not just re-projection.
    How accurate is this tool?
    It applies the published 3-parameter shift (EPSG::1148: dX=-130, dY=+110, dZ=-13), good to a few metres. Centimetre-grade work (stake-out, network adjustment) needs geodetic observation and a local fit — a service we provide.
